Picosecond Pulse Labs PSPL Model 5915: Custom-lowpass/rise-time filters have absorptive design

Users can build the PSPL Model 5915 filters to a –3-dB cutoff frequency ranging from 35 MHz to 10 GHz and a 10 to 90% rise time of 35 psec to 10 nsec. An absorptive design provides attenuation and group-delay characteristics similar to fourth-order Bessel-Thompson filters, claiming a superior transient response. The design provides a high impedance match in and above the filter passband. Additional features include a –15-dB typical return loss and a 0.02-dB insertion loss at dc. The filters provide compatibility with various standards and data rates, including SONET (synchronous optical networking), SDH (synchronous digital hierarchy), Gigabit Ethernet, PCIe (PCI Express), SATA (Serial Advanced Technology Attachment), and HDMI (High Definition Multimedia Interface). Available in a five-day turnaround time, the PSPL Model 5915 costs $495.
